>Was there a way to make the comments of every method of my class to be converted to the visual class using PRGTOVCX? I just found that all my comments were not moved.

Yes but they had to be formated in specific way.

DEFINE CLASS ...
*>*Mymethod*>*Here goes a comment ;
   second line of commennt ;
   and so on, up to 255 char max.
...

Look for 'ccVISUAL_DESCRIPTION' in the program for details.
